Dual Band Functionality (2.4 GHz and 5 GHz)

• Your adapter will automatically detect and connect to networks on either band.
• If your router broadcasts separate SSIDs for 2.4 GHz and 5 GHz (e.g., "MyWiFi_2.4G" and "MyWiFi_5G"), you can manually choose which band to connect to.
• For optimal performance, connect to the 5 GHz network if available and within range.
